Paver adhesive and method of laying pavers using same

Abstract

Disclosed herein are paver adhesives including dry concrete mixes. The paver adhesive can include cement, silica sand, alumina silicate, and latex or acrylic polymer. The paver adhesive can be configured to be applied to a substrate in a dry state. The paver adhesive can be configured to become hydrated subsequent to pavers being installed over the paver adhesive, and the paver adhesive can be configured to cure and adhere paver tiles to the substrate following the hydrating.

What is claimed is: 
     
       1. A dry concrete mix for dry setting paver tiles, the dry concrete mix comprising:
 cement; 
 silica sand in a concentration range from approximately 30 wt. % to approximately 75 wt. %; 
 alumina silicate; and 
 a latex polymer and/or acrylic polymer in a concentration range greater than or equal to 0.5 wt. % and less than 5 wt. %. 
 
     
     
       2. The dry concrete mix of  claim 1 , wherein the cement is in a concentration range from approximately 23 wt. % to approximately 70 wt. %. 
     
     
       3. The dry concrete mix of  claim 1 , wherein the cement is in a concentration range from approximately 21 wt. % to approximately 30 wt. %. 
     
     
       4. The dry concrete mix of  claim 1 , wherein the cement is in a concentration range of at least approximately 21 wt. %. 
     
     
       5. The dry concrete mix of  claim 1 , wherein the silica sand is in a concentration range from approximately 30 wt. % to approximately 75 wt. %. 
     
     
       6. The dry concrete mix of  claim 1 , wherein the alumina silicate is in a concentration range no greater than approximately 6 wt. %. 
     
     
       7. The dry concrete mix of  claim 1 , wherein the latex polymer and/or acrylic polymer is dry and redispersible. 
     
     
       8. The dry concrete mix of  claim 1 , wherein the latex polymer and/or acrylic polymer comprises poly(ethylene-vinyl acetate). 
     
     
       9. The dry concrete mix of  claim 1 , wherein the latex polymer and/or acrylic polymer is in a concentration range greater than approximately 0.5 wt. %. 
     
     
       10. The dry concrete mix of  claim 1 , wherein the cement is Portland cement. 
     
     
       11. The dry concrete mix of  claim 10 , wherein the Portland cement comprises:
 Type I cement in a concentration range from approximately 40 wt. % to approximately 60 wt. %; and 
 Type III cement in a concentration range from approximately 40 wt. % to approximately 60 wt. %. 
 
     
     
       12. A dry concrete mix for dry setting paver tiles, the dry concrete mix comprising:
 cement in a concentration range from approximately 20 wt. % to approximately 40 wt. %; 
 silica sand in a concentration range from approximately 30 wt. % to approximately 50 wt. %; 
 a water retention material; and 
 a latex polymer and/or acrylic polymer is in a concentration range no greater than approximately 8 wt. %. 
 
     
     
       13. The dry concrete mix of  claim 12 , wherein the cement is Portland cement. 
     
     
       14. The dry concrete mix of  claim 12 , wherein the latex polymer and/or acrylic polymer is dry and redispersible. 
     
     
       15. The dry concrete mix of  claim 12 , wherein the latex polymer and/or acrylic polymer comprises poly(ethylene-vinyl acetate). 
     
     
       16. The dry concrete mix of  claim 12 , wherein the latex polymer and/or acrylic polymer is in a concentration range greater than approximately 0.5 wt. %. 
     
     
       17. The dry concrete mix of  claim 12 , wherein the water retention material is alumina silicate. 
     
     
       18. The dry concrete mix of  claim 17 , wherein the alumina silicate is in a concentration range no greater than approximately 6 wt. %. 
     
     
       19. The dry concrete mix of  claim 17 , wherein the alumina silicate is in a concentration range from approximately 0.5 wt. % to approximately 6 wt. %.
